Algebra.Com's Answer #82411 by bucky(2189)![]() ![]() ![]() You can put this solution on YOUR website! False \n" ); document.write( ". \n" ); document.write( "The direction of the inequality symbol must be reversed when both sides of an inequality \n" ); document.write( "are multiplied or divided by a NEGATIVE number. \n" ); document.write( ". \n" ); document.write( "Remember this rule. It will be necessary to apply this rule in solving some inequality \n" ); document.write( "problems. \n" ); document.write( ". \n" ); document.write( "You can look at the rule this way: 3 is less than 5 which means that on the number line \n" ); document.write( "3 is to the left of 5. This is written as 3 < 5 \n" ); document.write( ". \n" ); document.write( "Now multiply both sides by -1. The inequality then becomes: \n" ); document.write( ". \n" ); document.write( "-3 < -5 \n" ); document.write( ". \n" ); document.write( "But this is NOT true because -3 is to the RIGHT of -5 on the number line and therefore \n" ); document.write( "it is greater than -5. So you have to reverse the direction of the inequality sign and \n" ); document.write( "make the inequality read: \n" ); document.write( ". \n" ); document.write( "-3 > -5 \n" ); document.write( ". \n" ); document.write( "Hope this helps you to see the reason the statement you were given is false. \n" ); document.write( ". \n" ); document.write( " |
